DRILL-TUBE FOR SEEDlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 334,683, dated January 19, 1886.

Application filed September 12, 1885. Serial No. 176,949. (No model.)

To all whom it may concern:

Be it known that I, GEORGE M. WILLIAMS, a citizen of the United States, and a resident of Newark, in the county of Newcastle and State of Delaware, have invented certain new and useful Improvements in Drill-Tubes for Seeding-Machines; and I do hereby declare th at the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a perspective view of a drilltooth for seeding-machines embodying my improvements. Fig. 2 is a bottom view of the same. Fig. 3 is a longitudinal vertical sectional view, and Fig. 4 is a vertical trans verse sectional view taken on the line 00 x in Fig. 3.

The same letters refer to the same parts in all the figures.

This invention relates to drill-teeth for seeding-machines; and it has for its object to provide a device of this class which shall possess superior advantages in, point of simplicity, durability, and general efficiency, by the use/of which the seed shall be always planted at an even depth, and the construction of which shall be such that cloggingshall be absolutely prevented. 1

With these ends in view the invention consists in the improved construction of the said drill-tube which will be hereinafter fully described and particularly pointed out in the claim.

In the drawings hereto annexed, A designates the body of my improved drill-tooth, which is provided at its upper end with a forwardly-extending bracket, B, and with a rearwardly-extending transversely-perforated lug, C, for its attachment, in the usual manner, to the frame of a seeding-machine. To the front side of the lower end or point of the drill-tooth is attached, in the usual manner, the blade or furrow-opener D. The lower end of the drill-tooth, or the point, as itis commonly called, is made of solid metal, as shown at E, and its under side, F, is made perfectly flat or level and at right angles to the front wall, G, of the opening or spout H.

The sides of the drill-tooth form shoulders or ofisets I I on the sides of the openings H, extending rearwardly, as shown, and the lower edges of which are level with the flat under side of the front end of the point. The heel end J of the point is somewhat raised, as shown clearly in the drawings, above the level of the under side of the front end, so that the seed will be dropped readily and without danger of being clogged. The front upper end and sides of the drill-tooth are equipped with a shield, L, which may be constructed of sheet metal, and which is directly below the seed-orifice of the planter, thereby dispensing with the flexible feeding or conveying tubes which are usually employed.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood by those skilled in the art to which it appertains without requiring any extended explanation. The construction is simple, and the expense of construction is no greater than that of drillteeth of the most ordinary construction. Vhen in practice a furrow is opened by the drill, the flat under side of the point of the drill-tooth serves to smooth or flatten and compact the bottom of such furrow, while the wings or shoulders I I, which extend rearwardly as far as the rear edge of the opening of the tooth, prevent the furrow from being clogged by the lumps of dirt before the seed has been deposited therein. These shoulders also serve to prevent pieces of straw or brush, manure, or the like from becoming wound or tangled around the point of the drill-tooth in such a manner as to interfere with the planting of the seed. Again, by the construction herein shown and described it becomes impossible for the seed to be dropped or deposited out of the furrow, or anywhere except at the bottom of the furrow, because on striking the vertical front wall, G, of the opening or spout H it will be instantly deflected to the bottom of the furrow, which has been prepared for its reception.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- The combination, with a drill -tooth for my own I have hereunto affixul my signature seeding-machines, of an upwardly-extending in presence of two witnesses. shield secured to the upper front end and sides thereof, said shield being directly below the GEORGE \VILLIAMS' 5 seed-orifice of the planter, substantially as and \Vit nesses: for the purpose set forth.

I I EDWARD MoPiKn, In testimony that I claim the foregoing as 1 7M. MCKEOWAN.
